Anyone ever replaced Rear Control Arm Bushings?
 
I am trying to press out and replace my rear control arm bushings on my 05 4.4 and am seeing MASSIVE scoring on the inner race of the control arm. I have have only removed one bushing so far as I don't want to screw up my control arm any further if I have done something wrong. 12ton Press and 50mm press sleeve. Just doesn't look or feel like other bushings I have pressed out in the past.

Did my e70 inner bushings a few months back and about to do my e53. The ones on the e70 didn't look pretty but I sanded them, put lube and the new bushings went in fine.
Maybe let them soak with some WD-40 or other penetrating lube before pressing them out?
YMMV.

If I have imperfect bearing / bushing race I'll find a bimetal hole saw about the exact size and use foam mounting tape to hold sandpaper and use a drill to hone the opening.

The LOWER control arms are $600 each. The two bushings needed for each arm are a total of $30 per side. Please tell me you don’t help people with money issues for a living. I am replacing EVERY bushing and ball joint on the whole vehicle. But I am not going to chuck an extra $1,200 at the thing for no reason. https://uploads.tapatalk-cdn.com/201...5eaacaabdf.jpghttps://uploads.tapatalk-cdn.com/201...1ad5efcaa5.jpghttps://uploads.tapatalk-cdn.com/201...65e363d156.jpghttps://uploads.tapatalk-cdn.com/201...1c8d62f5fb.jpg

In this post you indicated LOWER, I have not had any issue with my lower, only upper. That was my assumption.

Yes I am a retired broker, but I think it’s unfair you slam me, because you did not state which arms that were faulty.

Regarding pressing in new bushings, make sure there is ZERO play!

The swing arm bushings you are replacing have to be compressed to install. I would imagine if they don't have compression applied as they start to come out they will start to expand as they come out and cause damage. You will need to precompress the new ones with hose clamps or you'll never get them in.

I currently have them at -10f in the freezer as I have done with other bushings in the pas. I will heat the swing arm to expand it prior to pressing. But I will definitely take your advice about trying to pre compress the bushing prior to installing. The scoring on the bore was just odd and not like anything I have ever seen before. I have done a ton of bushing replacements but this set just was very different
